To read a spirogram, look at the flow-volume loop to assess lung function. The size and shape of the loop can indicate if there are any abnormalities such as obstructive or restrictive lung diseases. Key parameters to evaluate include forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and the FEV1/FVC ratio. Patterns such as a decreased FEV1/FVC ratio suggest obstruction, while reduced FVC may indicate restriction.
A spirogram gives a great deal of information about someone's breathing and the efficiency of their lungs.
A spirogram of a person with restrictive lung disease would show reduced VC, TLC, FRC, and RV.
The test produces a recording of the patient's ventilation under conditions involving both normal and maximal effort. The recording, called a spirogram, shows the volume of air moved and the rate at which it travels into and out of the lungs.
In a spirogram of a patient with emphysema, key lung values typically show a decreased forced expiratory volume in one second (FEV1) and a reduced FEV1/FVC (forced vital capacity) ratio, indicating obstructive lung disease. Additionally, total lung capacity (TLC) may be increased due to air trapping, while residual volume (RV) is also elevated. These changes reflect the impaired airflow and hyperinflation characteristic of emphysema.
